- * This file implements a CRIS decoder-stage in SW. The decoder translates the
- * guest (CRIS) machine-code into host machine code via dyngen using the
- * micro-operations described in op.c
- *
- * The micro-operations for CRIS translation implement a RISC style ISA.
- * Note that the micro-operations typically order their operands
- * starting with the dst. CRIS asm, does the opposite.
- *
- * For example the following CRIS code:
- * add.d [$r0], $r1
- *
- * translates into:
- *
- * gen_movl_T0_reg(0);   // Fetch $r0 into T0
- * gen_load_T0_T0();     // Load T0, @T0
- * gen_movl_reg_T0(1);   // Writeback T0 into $r1
- *
- * The actual names for the micro-code generators vary but the example
- * illustrates the point.
